SUMMARY

In recent times, the popularity of forage and livestock sector has increased at a very rapid rate throughout the country due to their important roles in employment generation and sustainable production. From last few decades, the problems associated with climate change have reached to a new height. Among these problems, the elevation in CO2 concentration has most disastrous impacts on forage production. This elevated level of CO2 decreases the quality as well as quantity of various fodder crops and trees. Impact of climate change varies from sector to sector depending on their inherent capacity of adaptation and vulnerability. Forage sector act as both contributor as well as source of adaptation to climate change. Generally, the crop simulation models are used at wider scale to assess the impact of climate change on crop production. With the help of these simulation models, various crop management decisions are made to provide alternative options to farmers for their farming system. Use of these models will increase in near future due to advancement in technologies and computer use. Various approaches of climate resilient agriculture have potential to mitigate the harmful impacts of climate change and thus raise the income of farm families. This paper provides an overview of impact of climate change on forage production and possible management strategies to mitigate its harmful impacts on forage crops for achieving sustainable production.

SUMMARY

The study was carried out to characterize the beef cattle production system and to characterize marketing system of the current smallholder cattle fattening practices. The study was conducted using questionnaire-based survey by interviewing a total of 120 household heads involved in cattle fattening practices selected by a systematic random sampling method from seven rural kebelles in the mid altitude and two kebelles in Low altitude agro-ecologies of Jabitehnan district in Amhara National Regional State, Ethiopia. Moreover, focus group discussions, field observations and Rapid Market Appraisal (RMA) techniques have been carried out. Descriptive statistics, one way ANOVA and DMRT for comparison of means were carried out using SPSS version 16 software and Chi-square (c2) test was employed to test the association of different qualitative categorical variables. The basal feeds were fresh cut green forage including improved forage and weeds took higher proportion (63.3%), followed by maize stover and stubble grazing (22.4%), pasture grazing (9.7%), and hay (5%). The three types of houses for fattening cattle are separated room in the family house (62%), enclosed barn with simple shade (22.4%) and housed together with humans (15.6%). Sources of fattening cattle were culled oxen due to old age or being unproductive (34.6%), immediate purchase for fattening (55.7%) and both culled oxen and immediate purchase (9.7%). Lack of capital and credit significantly affect (P<0.05) the practice in the mid altitude than in the low altitude. Average price of cattle before and after fattening were about 2297 and 3670 birr, respectively, which resulted in gross profit of about 1359 birr per fattened cattle that came from price margin and feed margin over 97 days of feeding period. It can be concluded that even though the cattle fattening practices carried out by smallholders are more of traditional; it could be one potential strategy to improve the income of smallholders if the present existing constraints could be avoided.

SUMMARY

There are a limited number of cultivated forage species in Saudi Arabia. The most common forage species is alfalfa (Medicago sativa L.). Therefore, hay production in the country is reliant on alfalfa and a few grass species. However, there is a tendency to standardize the productivity of this crop in the Kingdom due to its high water requirements. Large quantities of barley seed (Hordeum vulgare) are imported annually at exorbitant prices to meet the increasing demand for animal products. In addition, each of the important forage crops that are characterized by low water requirements compared to alfalfa, clover, and with its tolerance to heat and salinity, and high-energy content (carbohydrates). Thus, it is crucial to introduce other forage sources such as using silage to bridge the deficit in local forage crop resources. Silage is not commonly utilized as a source of animal feed among animal producers in Saudi Arabia, due to the lack of interest among animal producers. Thus, the aim of this review is to present information about the silage industry and the possibility of making silage from date palm residues as an alternative source of animal feed in Saudi Arabia.

SUMMARY

Combining ability is widely adopted and handy tool for comparing performances of parental lines in hybrid combinations in plant breeding experiments. It helps in understanding the nature of gene action for yield and its related traits. The present study was conducted to study the combining ability effects and estimation of economic heterosis for morpho-physiological traits related to fodder production, quality traits and anti-nutritional factors in sorghum which had a deep impact on fodder quality and in turn animal health. The material for the present investigation comprised of twenty-five hybrids developed using ten parents in line × testers mating design and two standard checks (SSG 59-3 and CSH 24MF). Observations were recorded for twelve morphological, four quality and 2 anti-nutritional parameters. Economic heterosis was estimated for all the characters. Six hybrids 31A × SSG 59-3 (139.1%), 126A × IS 2205 (131.15%), 14A × SSG 59-3 (109.24%), 94031A × SSG 59-3 (108.52%), 126A × HJ 541 (98.64%) and 14A × IS 2205 (76.09%) exhibited high significant positive economic heterosis for Green fodder yield in 1st cut. Female parent 14A was the best combiner for leaf length, GFY and DFY in 1st cut, protein content and HCN content. Whereas, the male parent 94031A was the best combiner for stem diameter, leaf: stem ratio, GFY and DFY in 2nd cut, phenol content and IVDMD. The IS 18551 was the best combiner for leaf length and HCN content. The correlation analysis revealed that GFY 1st cut had significant positive correlation with PH, DFY 1stcut at both genotypic and phenotypic level; and had significant negative correlation with stem diameter and IVDMD at both genotypic level and phenotypic level, respectively.

SUMMARY

The present investigation carried out to study per se performance and magnitude of heterosis in sorghum [Sorghum bicolor (L.) Moench]. The per se performance of parents revealed that the parent CSV 21F was top ranking for green fodder yield per plant and dry fodder yield per plant. The parent GFS 4 was found better for days to flowering, days to maturity, stem girth and protein content. The per se performance indicated that F1 hybrids GFS 4 × UTFS 91, PSVGS 313 × UTFS 91 and CSV 21F × GFS 4 recorded maximum green fodder yield per plant and dry fodder yield per plant among studied genotypes. The analysis of variance revealed highly significant differences due to genotypes for all the traits investigation which explained sufficient amount of heterosis was reflected in crosses for many of the fodder and grain yield attributing traits. Heterosis studies showed that plant height (cm), number of leaves per plant, stem girth (cm), leaf length (cm), leaf width (cm), leaf: stem ratio, green fodder yield per plant (g), and dry fodder yield per plant (g) were important forage yield components. A comparative study of best heterotic hybrid, GFS4 × UTFS 91 and PSVGS 313 × UTFS 91 for green fodder yield per plant and dry fodder yield per plant manifested significant positive heterosis over both better parent and standard check. These hybrids also exhibited significant and positive heterosis over better parent or combination of a standard check for various component traits viz., leaf width, leaf: stem ratio, dry fodder yield per plant, protein content and Brix value.

SUMMARY

The effect of different chemical treatments on nutritional quality and digestibility of wheat straw, rice straw, Sorghum sudan grass (SSG) and Guria grass (Chrysopogon fulvus) was investigated. The treatment with sodium chloride (2.00%), aqueous ammonia (10.00%), urea (4.50%) and dilute acid (1.50%) significantly improved the CP content of wheat straw (148.57%), rice straw (66.06%), sorghum sudan grass (SSG) (17.27%) and (30.24%), respectively. Alkali treatments [NaOH (2%) and Ca(OH)2 (0.4g/gm of sample)] were effective in reducing fiber and hemicellulose contents in wheat and rice straws while aqueous ammonia treatment was effective for treatment of SSG and Guria grass. Acid hydrolysis resulted delignification of feeds to the extent of 37.50%. Treatment of rice straw and SSG with sodium chloride resulted 21.62% and 57.58% increase in ash content, respectively. Highest increase in ash content of wheat straw (82.61%) and Guria grass hay (18.30%) was observed with dilute acid and calcium hydroxide treatments, respectively. Alkali treatments resulted significant reduction in phenolic content of straw and hay. The chemical treatments were effective in improving digestibility of fibrous feeds. The results of the study revealed that acid hydrolysis, sodium chloride, sodium hydroxide and aqueous ammonia, treatments had significant effect on improvement in nutritional composition and digestibility of wheat straw, rice straw, SSG and Guria grass hay, respectively.

SUMMARY

An experiment was conducted to study the effect of different cutting management schedules on growth, yield, quality and economics of dual purpose oat, barley and wheat during 2012-13 to 2014-15. The three year pooled data under cutting management revealed significantly higher green forage (54.3 t/ha), dry matter (9.15 t/ha), crude protein (0.93 t/ha), straw yield (10.02 t/ha) and green forage equivalent yield (78.31 t/ha) of oat,respectively. For dual purpose, oat variety RO-19 recorded significantly higher net monetary returns (Rs. 36033/ha) with B:C ratio (2.35) than rest of the crops. Whereas, seed yield (2.48 t/ha) was recorded significantly higher in the wheat crop. As regards to the cutting management, cutting at 70 days after sowing for fodder recorded significantly higher green forage, dry matter and crude protein yield (39.03, 7.12, 0.77 t/ha, respectively) than rest of the cutting managements. The seed and straw yield (2.48 and 9.40 t/ha) was recorded significantly higher in the no cutting for fodder and left for seed only on pooled mean basis; while, cutting at 50 DAS and left crop for seed recorded significantly higher green forage equivalent yield (79.45 t/ha), gross monetary returns (Rs. 63561/ha) and net monetary returns (Rs. 36128/ha) with B:C ratio (2.31). The pH, EC and organic carbon after harvest of crop remained unaffected. The differences are non-significant on pooled mean basis. The available N after harvest was recorded significantly higher i.e. 183.46 kg/ha in Barley crop. The soil available phosphorus (20.62 kg/ha) was recorded in wheat crop. While, available potash remained non-significant on pooled mean basis. As regards cutting management, no cutting for fodder and left for seed recorded significantly higher soil available N after harvest (173.46 kg/ha). The soil available phosphorus (20.78 kg/ha) was recorded at cutting at 70 DAS after sowing and left the crop for seed. The soil available potash remained unchanged due to cutting management on pooled mean basis.

SUMMARY

A varietal evaluation trial on perennial Cenchrus ciliaris (Buffel grass) was conducted at 13 locations under three different agro-ecological zones viz. North-western (NW), Central (CZ) and South (SZ) zones of India from 2016-17 to 2018-19. Six genotypes of Cenchrus ciliaris were evaluated along with three national checks viz. CAZRI 75, IGFRI 3108 and IGFRI 727 for assessing their fodder yield potential and quality parameters at CCS HAU, Hisar. The same set of entries was also tested at thirteen different locations distributed in the three zones for fodder trial. The highest green fodder yield pooled over three years (1317.2 q/ha) was recorded at Coimbatore in south zone followed by Urulikanchan (437.3 q/ha) in the central zone and in Hisar, Haryana (388.2 q/ha) whereas, the highest pooled dry matter yield (233.8 q/ha) was recorded at Coimbatore in south zone followed by Urulikanchan (195.8 q/ha) and Hisar (91.1 q/ha) in the central zone. Highest per day productivity of green fodder pooled over three years was recorded at Hisar, Ludhiana and Jhansi (GFY (q/ha/day – 4.03, 3.27 and 3.0, respectively) in different zones. The national check CAZRI 75 gave highest green fodder yield (543.5 q/ha) and the genotype IG-67-365 gave highest dry fodder yield (400.8 q/ha) pooled over three years. The highest crude protein yield pooled over three years was obtained at Urulikanchan (12.1 q/ha) followed by Anand (7.2 q/ha) and Hisar (5.3 q/ha). Top two genotypes that gave the best crude protein yield are IG-67-365 (6.0 q/ha) and the best check CAZRI 75 (5.5 q/ha) pooled over three years. Cenchrus ciliaris genotype RCCB-03-23 gave In vitro dry matter digestibility (IVDMD%) pooled over three years (53.9%) which is almost at a par with the best check IGFRI 3108 (53.7%). At Hisar, the Cenchrus ciliaris genotype RCCB-04-3 gave Neutral Detergent Fiber (66.8%) as compared to the best check IGFRI 3108 (69.1%). The genotype RCCB-03-23 gave Acid Detergent Fiber (ADF%) (42.5%) as compared to the best check IGFRI 3108 (43.5%). A close look at the data reveals that Southern zone gave higher green fodder and dry matter yields, plant height and production efficiency thereby indicating that climatic and edaphic conditions are very suitable for Cenchrus ciliarisas compared to Central Zone and North West Zone.

SUMMARY

Quality green fodder production throughout the year is the major drive for increasing the livestock productivity in the country. In this regard, a filed investigation was conducted at Zonal Agricultural Research Station, Vishweshwaraiah Canal Farm, Mandya, Karnataka during 2018-19 and 2019-20 to identify the suitable cropping system for year round quality green fodder production under irrigated condition. The experiment was conducted with fifteen different cropping systems involving both annual and perennial cereal and legume fodder crops in randomized complete block design and replicated thrice. The pooled data revealed that, the perennial B×N hybrid + Lucerne system at 2:8 proportion recorded higher green fodder yield (1636q/ha/year), dry matter yield (321q/ha/year), crude protein yield (60.2 q/ha/year), gross returns (Rs. 3,02,440/ha/year), net returns (Rs. 2,14,232/ha/year) and benefit cost ratio (3.4) followed by B×N hybrid + Cowpea (2:8) and B×N hybrid + Sesbania (2:8) perennial systems and proved as viable systems for obtaining higher quality fodder.
